摘要
分别概述了高、低能乳化法的技术原理,并分析了不同乳化法的技术特点及应用现状。通过借鉴纳米乳液的制备方法,结合缠结聚合物的结构特性以及纳米乳液体系中有机相的分子量低、易变形特性,分析出高能乳化法制备缠结聚合物分散液的缺陷,确定低能乳化法中的相转变法是实现缠结聚合物分散液制备的方法。结合相转变温度法(PIT)和相转变组分法(PIC)对乳化剂曲率变化的影响,确定了PIC法制备缠结聚合物有机分散液的技术可行性,并对缠结聚合物应用领域的拓展进行了技术展望。
The technical principles of high and low energy emulsification methods were summarized respectively,and the technical characteristics and application status of different emulsification methods were analyzed.Inspired by the preparation method of nano emulsions,combining the structural characteristics of entangled polymer and the low molecular weight and easy deformation characteristics of organic phase in nano emulsion system,the defects of preparing entangled polymer dispersion by high-energy emulsification method were analyzed,and the phase inversion in the low energy emulsification method could be used to prepare entangled polymer dispersion.The technical feasibility of preparing organic dispersion of entangled polymer by PIC method was determined by combining the effects of phase inversion temperature(PIT) method and phase inversion component(PIC) method on the curvature change of emulsifiers,and the expansion of the application field of entangled polymer was prospected.
